ok,
your 100% right.
my input on headers from what i have seen:
-if you are worried about spending alot of money for a kw gain , go for some 4-2-1 hurricane headers ( i got a 5-7kw gain from them and so did the guy i sold them too i think).the only problem is they look a bit dingey and my mounting bracket snapped.
-If you want the best output from a blot on go the toda's......they are developed through testing rather then cheap copy's and they also look bang on, and we all need a bit of charictor in our engine bay's.
